WIRE STRAIGHTENING AND CUTTING-OFF MACHINE.

Application filed April 28, 1920.

To all "La/r0022 it may concern: I

Be it known that I, ELMoRn F. SiIUsTnR, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Wire Straightening and Cutting-Off Machines 5. and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wire straightening and cutting off machines, and is an improvement on the construction shown and clescribed in the patent granted to me on August 12, 1919, No. 1,313,021. One of the objects of this former construction was to make the worm gear a detachable element of the gear combination rather than positively locating it in the machine frame. he present construction is specially adapted to feed and cut wire of larger size than the former machine is capable of. For large wire it is necessary to employ initial feed rolls to break down the heavy wire beforeit enters the straightening arbor, and to halt these rolls while the cut off lever is severing a wire section. To stop and start these rolls requires certain shipping mechanism which could not be applied to the former constructionwithout interfering with its worm and worm gear mechanism. 7

Referring to the accompanying drawings, wherein the same figures and letters of reference indicate like parts throughout the several views;

Figure 1 is a plan view of the machine head and broken view of the motor, guide bar and rock shaft.

Fig. 2 a side elevation of the machine head, showing the sprocket chain removed and sectional view of the motor shaft on line 2-2 of Fig. 1, also broken View of the guide bar and rock shaft, and

Fig. 3 is a front elevation of the machine head, sectional view of the guide bar and rock shaft.

The several improvements of the present invention relate to the head 1, the remainder of machine, with which the guide bar 2 and rock shaft 3 connect, being old and well known, is not shown.

The shaft 4 of the motor 5 carries the pinion 6 meshing with the gear 7 to drive the worm gear shaft 8 journaled in the Specification of Letters Patent.

standard 9 and also in the head 1. 10 is the worm gear meshing with the worm 11 mounted on the arbor 12 journaled in the standards 13.

g The initial feed rolls ll, 15, 16, 17, and 18, Fig. 1, are mounted on the ends of the shafts 19, 20, 21, 22, and 23, Fig. 2, and are adjusted with respect to the wire by the screws 2-1 and 25, mounted in the housings 26 and 27. The gears 28, 29, 30, 31, and 32, mounted on these shafts, and also the idle gear 32, are intermittently driven from the worm gear shaft 8 as follows:

The pinion 33, Figs. 2 and 3, meshes with the clutch gear 34: journaled on the clutch shaft 35 and this shaft is rotated when the clutch plate 36 engages the gear 34. The pinion 37, see also Fig. 1, on shaft 35 meshing with the gear 38 on the feed roll shaft 19, rotates said shaft, thus communicating the proper rotative movement to the feed roll shaft. The outer end of clutch shaft 35 is journaled in the standard 9 and the outer end of shaft 19 is journaled in the bracket 39, Figs. 1 and 2.

Intermittent rotation is imparted to the cam shaft 4:0, through the medium of the pinion 41 on the worm gear shaft 8, actuating the gear train e2, 43, a l, journaled on the studs d5, 46, d7, to rotate the large gear d8 journaled on the cam shaft 40 secured to the balance wheel l9 on said shaft. The balance wheel, cam 50, cut off lever 51, are well known features in' machines of this character, especially the trip lever 52, which engages thekey 53, the releasing of which, by the trip lever, will engage the balance wheel with the shaft. The wire 54: connects with well known trip-ping mechanism on the forward part of the machine, not shown. The forward feed rolls 54:, 55, Fig. 3, their shafts 56, 57, connecting gears 58, 59, for said shafts, are also well known features. The sprocket chain 60, Fig. 1, connects the sprocket wheel 61, on the forward feed roll shaft 57, with the smaller sprocket wheel 62 on the rear feed roll shaft 19.

The shipping lever 63, Fig. l, is pivotally connected to the bracket 6& by the screw 65. One end of this lever engages the forked sleeve 66 secured to the clutch plate 36. The opposite end of the lever, Fig. 3, carries the roll 67 adapted to engage the cam 68, which cam actuates the lever to connect and disconnect the clutch plate 36 with the clutch gear 34. 1

clutch shaft 35, and through its'pinion 37, transmit motion to the gear 38 onthe feed roll shaft 19. As soon as the pro-per length of wire has passed through the arbor, the lever 63 is actuated by the cam'GS todisconnect the clutch late 36 and bring the clutch shaft 35, pinion 37, gear 88, feed roll shafts 19, 20, 21, 22, 23, 56 and 57 to a standstill. Directly the above named elements have, been halted the tri) lever 52 is actuated inthe manner be ore mentioned, to bring the looselyrunning gear 48 and balance wheel 49 into engagement with the cam shaft 40, which shaft is then rotated to actuate the cut off lever 51 through the medium of the continuously running gears 41, 42, 43 and 44. As soon as a. section of wire has been cut, the cam shaft is halted and the feed rolls are again automatically brought into action. In feeding large wire, as be fore mentioned, it is absolutely necessary to halt the feed rolls to prevent marring the wire while the cut off lever is in action.

The varying sizes of the several gears and sprocket wheels are so arranged and con structed as to transmit toeach of the moving elements the proper speed and timing necessary for each to automatically'and continuously perform'its proper functions.

It will be understood that where I use the term motor to drive the mechanism, it includes a pulley or other well known means for transmitting power.

Havmg thus described my 1nvention,what I claim is:

1. In a machine of the character describedv rhavlng a head, a straightening arbor ournaled in the head, a worm on the arbor, cam shaft, and-cutting off lever, forward and rear worm gear shaft, a worm gear thereon 'meshing with the arbor gear, a gear on the lat- Iter shaft meshingwith .th'emotor shaft gear,

a clutch shaft, a clutch plate and a clutch gear mounted thereon, a gear on thefworm gear shaft meshing with the clutch gear, a pivoted lever connected with the clutch plate, a cam on the cam shaft controlling said lever, agear and a sprocket wheel mounted on one ofthe rear feed roll shafts,

a gear onthe clutch shaft meshing with the feed roll shaft gear, a sprocket wheel mounted on one of theforward feed roll shafts, and driving means uniting the sprocket wheels to rotate all of the feed rolls.

- 2. In a machine of; the character-described having a head, a straightening arbor, a worm on the arbor, forward andrear feed-rolls and shafts therefor, a camshaft and cutting off-lever, a balance wheel on the cam shaft, a gearsecuredto the balance wheel, ofmechanism for feeding and straightening the wire, cutting off predetermined lengths of wire, and halting the wire feed during, the cutting, comprising a -continuously running motor shaft,;a pinion there- ,on, a wormigear shaft, a gear thereon meshing with said pinion anda worm gear meshing with the'arbor worm, a clutch shaft, a
